The besetting hindrance to their progress was the low scrub of brushwood that greatly delayed the pack-horses. This obstacle was overcome only by patiently advancing before the horses every afternoon, and cutting a bridle-track for the succeeding day's stage. Thus literally, the way that ultimately led into the interior was won by foot, and the little pioneering band eventually descended into open grazing country at the head of what is now known as the Cox River. The outward and return trip occupied less than one month's time; which speaks volumes for the wise choice of route; but what says more, is the fact that no better natural, upward pathway has since been found.
Routes of Blaxland, Wentworth, and Lawson (1813); Evans (1813); Oxley (1817, 1818, 1823); and Sturt (1828 and 1829).
A synopsis of Blaxland's journal is given here, commencing with a few quoted lines of preamble:--
"On Tuesday, May 11th, 1813, Mr. Gregory Blaxland, Mr. William Wentworth and Lieutenant Lawson, attended by four servants, with five dogs and four horses laden with provisions and other necessaries, left Mr. Blaxland's farm at South Creek for the purpose of endeavouring to affect a passage over the Blue Mountains, between the Western River* and the River Grose … The distance travelled on this and subsequent days was computed by time, the rate being estimated at about two miles per hour."
*[Footnote.] The Warragamba.
They camped at the foot of the ridge that was to witness the last struggle between man and the Mountains. On the first day, they did three miles and a half in a direction varying from south-west to west-north-west, and that night obtained a little grass for the horses, and some water in a rocky hole.
The heavy dews in the morning retarded any attempts at early departures, as the thick wet brush rendered it difficult to drive the horses, so that, as a rule, it was nine o'clock before they were able to strike camp. The ridge, still favouring the direction of west and north-west, on the third day they arrived at a tract of land, hilly, but with tolerable grass on it. Here they found traces of a former white visitant in the shape of a marked-tree line. Two miles from this point, they met with a belt of brushwood so dense that for the first time they were forced to alter their course; but the subordinate spurs on either side ending in rocky precipices, they had to return and again confront the scrub. In these circumstances, they made up their minds to rely upon axe and tomahawk to win a way, and so next morning fell to work cutting a passage for the horses. The ascent was also now becoming steep and rough, and on this day some of the horses fell while struggling up with their loads.
The first day's work gained for them five miles, but at the end of their toil they had to retrace their weary way back to the last night's camp. The next day they cleared the track for only two miles further ahead; so much time being wasted in walking backwards and forwards to the work. There was no grass amongst the scrub that encompassed them, and when, on Monday, they determined to move the camp equipage forward, they packed the horses with as much cut-grass as they could put on them. This amounted to, according to Lawson's diary, about two hundred pounds weight for each horse, which, in addition to their ordinary loads, must have been a very weighty packload for uphill work. However, according to Blaxland, "they stood it well." They obtained no water for their animals that night, and what they wanted for their own requirements had to be painfully carried up a cliff about six hundred feet in height. On the succeeding day they suddenly came on what at first appeared to be an impassable barrier. The ridge which they had so pertinaciously followed, had, for the last mile narrowed and dwindled down into a sharp razor-backed spur, flanked with rugged and abrupt gullies on either slope. Across this narrow way now stretched a perpendicularly-sided mass of rock, which seemed effectually to bar their path. The removal of a few large boulders however, revealed an aperture which, after some labour, they widened sufficiently to allow the pack-horses to squeeze through.
Once through they began to ascend what they estimated to be the second tier of the Mountains. Shortly after they left camp that morning they came on a pile of stones, or cairn, evidently the work of some European, which they attributed to Bass. They were much elated at the thought that they had now passed beyond the limit of any previous attempt.*
*[Footnote.] This cairn was afterwards named Cayley's Repulse by Governor Macquarie: but recent research goes to show that Cayley followed the valley of the Grose, and was many miles to the north of where the cairn was found. According to Flinders, Bass was not on the high ridge traversed by Blaxland and party.
They could now look round with triumph on the panorama spread beneath their view, and from the superior elevation which they had obtained, they took the bearings of several noticeable landmarks that they had seen before only from the flat country. The labour of cutting a path each day for the horses for the next day's march had, however, still to be continued; but the crest of the ridge was again wider, though the gullies on each side were as steep as before. That night, in camp, the dogs were uneasy throughout the night, and several times gave tongue and aroused the sleepers, tired with their day's work. From what they found afterwards, they had good reason to believe that the blacks had been lurking around meditating an attack.
They then passed over the locality known in the present day as Blackheath, and soon afterwards had their course diverted to the northward by what Blaxland terms "a stone wall rising perpendicularly out of the side of the mountain." This they tried to descend, but without success, and so kept on along its brow. Undergrowth still delayed them, and they still had to spend their energies in hewing a passage, until on the 28th of the month, they camped on the edge of the steep descent that had lately marched beside them. The decline was, however, not quite so abrupt, and the face no longer composed of solid rock. They paused to overlook what lay before them and immediately below, and found the view more gratifying than they had anticipated. What they had at first taken for sandy barren soil proved now, on nearer inspection, to be forest-land fairly covered with a good growth of grass. The horses not having tasted fresh grass for some days, they cut a slanting trench across the sloping face of the descent in order to afford the horses some sort of foot-hold, and managed to get them down to a little feed that evening.
Next morning they were up and away early, and reached the foot of the mountain (Mount York) at 9 a.m., having had to carry the pack-loads down most of the way themselves, as it was too steep for laden horses to preserve their balance with safety. The actual base of the mountain was reached through a gap in the rocks, some thirty feet in width.
They now found themselves on what was then termed meadow land, drained by the upper tributaries of the Warragamba; and this country presenting no serious obstacle to their further progress, they rightly concluded that they had now surmounted every difficulty. They followed the mountain stream up for some distance and, at the furthest point they reached, ascended a high sugar-loaf hill, which surveyor Evans, who followed in their footsteps, called Mount Blaxland. From the summit they had an extensive view all around, and Blaxland described the character of the country they saw in the following words: "Forest and grass land, sufficient to support the stock of the colony for the next thirty years."
Just here, let us compare this prophecy with a similar one made by Evans a few months afterwards, on the pasture lands of the upper Macquarie: "The increase of stock for some hundred years cannot overrun it."
The provisions of the explorers were now nearly expended; their apparel, especially their footgear, was in rags and tatters; on the other hand, the work that they had set themselves to do was well done. They had vanquished the Blue Mountains. Their return was uneventful. After breakfast on the 6th of June, they crossed the Nepean, their provisions, with the exception of a little flour, being quite consumed. We thus see how in the end the impenetrable range, that had so long overawed the colonists with its frown, was overcome, with slight difficulty, when local experience combined with method, was arrayed against it. To liken the former expeditions to Blaxland's is to compare a few headlong assaults with a well-conceived and skilfully worked-out attack. The men themselves
